Given that Pollock is by far the best bowler of the 6, I'd choose the South African trio. More room to do so.

Sreesanth said, "Next ball he was beaten and I said, 'is this the King Charles Lara? Who is this impostor, moving around nervously? I should have kept my mouth shut for the next ball - mind you, it was a length ball - Lara just pulled it over the church beyond the boundary! He is a true legend."

Definately the South African trio. Pollock is the only quality bowler of the six and Gibbs and Boucher would also be two of the most destructive batsmen on their day (both have ODI scores of around 150). The NZ trio have shown in recent times what they're capable of but they haven't done it for as long or with the consistency of the South African trio.

We're talking of an X factor here, so the less fancied the player is, the more dangerous they are. While the South Africans are obviously better on reputation, the Kiwi trio can spring up a major surprise. This comparison isn't equal, unless you take everything into consideration, inclding batting, bowling and fielding of all in question.

Yeah in the Odi games you can turn things now and again, but when you have to do it more consistently then thats where talent and skill matters and thats where the South African trio are way ahead of the Kiwi trio
